Revolution or War is the journal of the International Group of the Communist Left (IGLC). It is the result of the fusion of CIK- Klabastalo and FICL which dissolved beforehand in November 2013. Our unity is based on the following main points:1 – For our class, this vital unification of Left Communist forces (whose main component is the ICT) is an essential step for the future and indispensable formation of the class party for the revolution. This fundamental objective also requires uncompromising struggle against the penetration of bourgeois ideology within the Communist Left, especially against the opportunism and sectarianism that still plague this environment.2 – Today, this necessary process can only strengthen communists’ ability to assume the responsibilities that the proletariat has raised: to be its most conscious and determined fraction.
